JOSEPH M. WHITMORE, OF HOBART, INDIANA, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO ROBERT E. MILLER, OF SAME PLACE.

OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 226,010, dated March 30, 1880.

Application filed May 7, 1879.

To all whom it may concern:

Be it known that I, J OSEPH M. WHITMORE, of Hobart, in the county of Lake and State of Indiana, have invented a new and useful Improvement in Oil-Stoves, of which the following is a specification.

My invention is an improvement in oilstoves.

It consists, principally, of certain improvements in the oven, which is hinged to the upper part of the body of the stove and rendered capable of being thrown back and supported out of position without being detached.

It consists, secondly, of a deflecting-pan, constructed as hereinafter described, to retard and deflect the heat coming from the lamp and cause it to be diffused evenly over the oven-chamber.

It consists, also, of certain improvements in the general construction of the stove, which will be pointed out in the following detailed specification.

In my drawings, Figure 1 is an elevation of my stove with the cover of the oven thrown back. Fig. 2 is a perspective view of the same; Fig. 3, a vertical sectional view across the center of the stove, showing the various parts in relation to each other. Fig. 4 is a top view of the upper plate of pan M; Fig. 5, a perspective view of the iron heater and heat-radiator. Fig. 6 is an elevation of oventop support.

Similar reference-letters indicate like parts in all the figures.

Referring to drawings, A is the base of the stove, formed of sheet-iron or other suitable material, which contains within itself an independent oil-reservoir, B. This reservoir is cylindrical in form, and is provided with a vertical opening through its center in the form of a tube. An inlet-tube, V, located in the upper plate of said reservoir, is provided to receive the oil, and is kept closed when the stove is in use by a cap of the ordinary form.

C G are the wick-tubes, which are inserted in the upper plate of the reservoir B on either side of the opening in its center previously mentioned. Around the tube 0, and resting on the base A, is the body-support D, which forms a hollow square, within which is fixed a perforated plate or fine gauze diaphragm, E, to check the vibration of the air and steady the flame. \Vick-tubes (J 0 pass through and extend above this plate or diaphragm, and they are provided with the usual device for raising and lowering the wicks.

Resting on the upper edge of the body-support D, and slightly outside of it, is a light cast-iron plate, F, having a flange on its lower surface, which fits close to the perforated plate E. A pin under each front corner fits into the corners of the support D, and a hole in each back corner receives the ends of the hinge G. The hinge G consists of a wire bent in a U shape, whose middle is firmly clasped the full length by a fold of sheet metal fastened to the body-support D or base A, and whose ends pass upward through holes provided in the back corners of the plate F, being secured by small nuts above. A clasp, H, riveted to the cylinder J, catches on a pin in the body-support D, to secure the said parts J and D together. On the upper surface of the plate F, immediately above the wick-tubes O, are upwardly-projecting cone-frustums j, which form openings to conduct the heat toward the upper part of the stove. I I are oval tubes of sheet metal, which serve as chimneys to facilitate the draft. These tubes are formed tapering toward their tops, and are provided with mica lights in their sides, through which the flame from the wicks may be observed. Surrounding the tubes I I is a cylinder, J, which fits snugly onto the plate F, which forms its support. The said cylinder J is provided in front with openings 12, coinciding with the mica lights in the chimneys, through which may be seen the flame of the lamp.

On top of the cylinder J is a casting, K, furnished with a projecting cornice, to serve as a support to a hollow projecting pan above. The chimneys I I are fixed to the casting K, so that they may be lifted with it when said casting is removed.

The plate F and casting K, when the stove is prepared for use, are firmly secured together by a bolt with suitable nuts, which passes through holes provided for it in the centers of said casting and plate. From the central portion of casting K spurs or pins to arise, to serve as bearings to vessels used in cooking or for sad-irons. I

In the casting K are lugs, which receive four pairs of double legs, to support the upper perforated plate of pan M. This pan M is a little wider than the cylinder J with its annular projection, and considerably longer than its width. It has an upper and lower plate, both of which are perforated, and vertical walls on all four sides. The lower plate has an opening in its center about the diameter of the cylinder J. The upper plate of the pan M has also an opening about the size of and immediately over the opening in the lower plate. In the top and bottom plates of said pan are perforations, to allow a free entrance and circulation of air from the outside. The pan M forms the base of the oven, which has for its cover the top 0.

Passing through the back part of the upper plate of the pan M are two or more staples or hooks, N, which hook into the wire edging of the top, and are secured to the vertical wall a of the said pan. These staples serve as hinges, and, being open, as seen in drawings, form a ready means of attaching and detaching said ovens top or ,cover.

The cover 0 of the oven is similar in form to an inverted box, and is a trifle smaller than the upper plate of the pan, which forms its rest. Said cover or top is lined at its top to form a chamber or air-space, 0, to serve as a flue for the exit of hot air when a great heat is not required in the oven. At one side of this lining is an opening, 0 to allow the hot air from the oven to pass in directly to a damper, a, in the ovens top plate. The support P is formed of wire of a U shape, and is clasped at its middle by a fold of sheet metal, which is firmly riveted to the back of the ovens top, being allowed to swing freely within said clasp, as by a hinge. This swinging support may be strengthened by braces f g. (Shown in drawings.) l

Within my oven I place a deflecting-pan, Q, which I support upon suitable legs over the openings in the top of the stove. This pan is formed of a series of V-shaped plates secured together at their ends, which are placed parallel to each other. They are nearly the length of the ovens width. This pan, from its peculiar construction, answers theimportant purpose ofpreventing a too rapid movement of the heat upward, while it serves to diffuse and evenly distribute it throughout the oven.

As an addition to my oil-stove, I provide a cylindrical heat-radiator, R, which is formed of sheet metal, contracted at its base to allow it to set into the top of the stove. Ithas three vertical slots at regular distances apart in its cylinder, running from the top nearly to the bottom, and aconical cap or top. This device serves the double purpose of protecting sadirons while heating or for warming a small apartment by radiation. The three vertical slots 12 are provided for the handles of the irons,

which rest on the spurs w. The heat-radiator It serves to confine the heat and prevent it from ascending too rapidly.

In the use of my improved stove, after the wicks are lighted a draft is formed upward through thetube in the middle of the oil-reservoir, passing about the wick-tubes in the hollow square chamber D. It is obstructed and steadied by the plate or gauze E, and passes thence above the flames through the chimneys I and into the pan M. Here it is mixed with and tempered by the cool air coming from the outside through the perforations in the pans bottom plate and vertical walls before passing into the oven. The rack Q forms an obstruction to the direct draft and facilitates the mixing of the hot and cool air to temper it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The oven-top 0, provided with the space 0, with opening 0 and damper to, having as its base the projecting perforated pan M, as and for the purpose set forth.

2. The stove composed of the oil-chamber B, provided with draftopenin g B and supported by base A, the hollow chamber D, through which passes the wick-tube G C, and provided with a gauze or perforated diaphragm, E, the cylinder J, having attached to its top plate or casting the chimneys I, in combination with the oven composed of the pan M and top 0, all

arranged substantially as and for the purpose set forth.

3. In combination with the oven, composed of pan M and cover 0, the deflecting-pan Q, composed of a series of V-shaped plates secured together at their ends, as and for the purpose set forth.
